This should come as no surprise, but you should really only use cannabis and cannabis-based materials in your herbal vaporizer. That being said, certain devices will only work with specific materials, though there are vaporizers that work with both. Knowing what you can actually put in your vaporizer will save you a lot of headaches and should be outlined in the manual included with your device.
When looking at herbal vaporizers, there are three main types of material that can be used.
- Dry herb
- THC oil
Out of all these materials, THC oil is the only substance that is confined to a single type of device, whereas there are devices that can properly vape dry herb and wax/concentrates.
Regardless of what material you can use, be sure to only purchase them from reputable brands and manufacturers.
